Short answer: the JBL Partybox Encore Essential 2. It ranks #6 of 113 boombox speakers by sound quality, rated 4.3/5, at $249.95. The Gemini GGO-650L ranks #86, rated 2.5/5, at $99.95, $150 cheaper, a saving that is not big enough to make up the sound-quality gap.
The JBL Partybox Encore Essential 2 is the better-sounding, deeper-bass pick. A compact party speaker with balanced sound, punchy bass, mic and guitar inputs, and enough volume for a backyard party. Its bass reaches about 42Hz before falling 10dB, against 56Hz for the Gemini GGO-650L. It is rated for 15 hours of battery against 10 for the Gemini GGO-650L. It links with other speakers (Auracast), which the Gemini GGO-650L cannot. Watch for: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
The Gemini GGO-650L is the lighter choice. An inexpensive stereo party speaker with a big woofer, water resistance and a 10 hour battery. At 9.3 lbs (4.2 kg) it weighs noticeably less than the JBL Partybox Encore Essential 2 at 13.7 lbs (6.2 kg).
Buy the JBL Partybox Encore Essential 2. It is rated higher for sound quality, and the $150 saving on the Gemini GGO-650L is not enough to make up the difference.
